According to the hypothesis of the technological-humanitarian balance, mankind throughout its history has maintained a balance between three variables: the technological potential, the quality of cultural psychological regulation and the inner stability of society. One of the consequences of the hypothesis is that with the increase of the destructive power of weapons and demographic density of population the ratio of violence victims to population did not increase, but decreased, which was the result of regular elimination of societies with decompensated aggression. Observation and calculations seem to confirm that paradoxical suggestion.
